FastNoise VS webgl-noise

If you go to the FastNoiseLite github you'll see there's a FastNoiseLite.glsl file, this file contains the entire library. So to use this in a shader we need to use the new shader #inlude preprocessor. In short, create a new ShaderInclude resource, paste the contents of the FastNoiseLite.glsl file into it and then simply #include it in your shader.

FastNoiseLite: ValueNoise, OpenSimplex2, OpenSimplex2S, Perlin, ValueCubic (from https://github.com/Auburn/FastNoiseLite )

Fair enough. If it helps, you can drop this into a P5.js sketch without too much friction: https://github.com/Auburn/FastNoiseLite/tree/master/JavaScript

I suppose I'll compile what I can find here for future searchers: Here's the original github for FNL , it has some images to use as examples but few explanations unless you want to download and run the preview program yourself.

Also take a look at FastNoiseLite if you want better control over noise generation, and for cool examples.

I used this repo: https://github.com/Auburn/FastNoiseLite

Yeah, that's literally what a seed does. It's really odd to me that the unity mathematics one doesn't have a seed. I use this one: FastNoiseLite

I really like this library which appears to have gals implementation. https://github.com/Auburn/FastNoiseLite

For the actual dunes I used fast noise lite ( https://github.com/Auburn/FastNoiseLite ). They have a nice gui app, where you can create noise textures (in my case voronoi noise). Then I apply the height map to the individual terrain tiles. So no fancy procedural Generation is going on here.

you may want to start with (4d cellular) ashima-simplex-noise functions of https://github.com/ashima/webgl-noise as basis function, as this is not convergent+iterative like other procgen functions (that are more like a convergent game-of-life). demos of them are in https://www.shadertoy.com/results?query=ashima&sort=newest&filter=

Oh nice. I think the GLM noise is actually based off the Ashima Arts + Stefan Gustavson GLSL noise https://github.com/ashima/webgl-noise

Oh I see what you mean now. Not saying https://github.com/KdotJPG/OpenSimplex2 isn't safe, just that https://github.com/ashima/webgl-noise/blob/master/src/noise3D.glsl isn't. Ty for clarifying, makes perfect sense now!

Several years ago when I was experimenting with all of this I found that OpenSimplex was significantly slower than regular Simplex (not sure what library I was using). Maybe it's improved since then? Anyway, I've since moved my noise computation to the GPU and speed is less of an issue for that particular project. I'm currently using the simplex noise function from GLM, which comes from https://github.com/ashima/webgl-noise. Do you have any idea how that compares with the various noise functions you've listed?
